Subject: Watermarks research project
The Conservation of Fine Art Unit and the Institute for Image Data Research (IIDR) at the University of Northumbria at Newcastle, UK are undertaking a collaborative project involving the development of a shape retrieval system for watermark images from works of art on paper. The aim of the project is threefold: 1. The development of automatic shape retrieval techniques for watermark images. 2. The development of current research on techniques for extracting usable watermark images from works of art on paper using Dylux, transmitted light, Beta radiography, Microfocus radiography, ultraviolet and infrared techniques, digital manipulation etc. 3. The compilation of a content-accessible archive of watermarks (The Northumbria Watermark Archive) on the web to serve as a live and dynamic research tool for art historians, paper historians and paper conservators. The project will apply techniques developed for the IIDR's ARTISAN software written for the retrieval of trademark images by shape. It will allow users to introduce a query image (or part image) and search for similar watermark images in the database. This will be supplemented by the appropriate textual metadata. The software differs from other content-based retrieval (CBIR) systems in its exploitation of Gestalt principles in human perception of shape, rather than utilising algorithms that simply look for similar coloured pixels in corresponding locations in a given image. It is intended that the active database will include not only historical information on papers and watermarks (origin, information about the mill, papermaker, dates etc.) but also information more relevant to conservators (technical data about the paper used, aging properties, artists known to have used the paper, how the paper behaved during /after treatment, case studies etc.) It is hoped also that the database will be a resource that researchers and conservators will contribute to. We believe that it will be a useful supplement to the wealth of information currently available on watermarks and paper. A more detailed explanation of ARTISAN and the objectives of the project is available at (<URL:http://www.unn.ac.uk/iidr/research/wmarks/wmarks.html>). We would appreciate any thoughts and comments about the project from conservators, art historians etc. Correspondence can be sent to: r.mulholland [at] unn__ac__uk or by post to: Richard Mulholland Research Assistant/Conservator Conservation of Fine Art Burt Hall University of Northumbria Newcastle NE2 4LR Fax: +44 191 2273250 *** Conservation DistList Instance 14:31 Distributed: Wednesday, November 29, 2000 Message Id: cdl-14-31-007 ***Received on Friday, 24 November, 2000
